Lucien Guitry
Lucien Germain Guitry was a French actor.
In 1885, while living in Saint Petersburg, he appeared at the French Theatre. His son, the future actor, writer and director Sacha Guitry, was born in Saint Petersburg and named in honour of Tsar Alexander III. Lucien met the composer Pyotr Ilyich Tchaikovsky and his brother Modest, and became good friends with them. It was at Guitrys instigation that Tchaikovsky wrote both his Hamlet OvertureFantasy in 1888, and the Incidental Music to the Shakespeare play in 1891, for which he reused the overturefantasy in shortened form as the overture.
